HACMP Tidbits Tidbits from Shawn Bodily: - First and formost, TSM does NOT work with HACMP v5.3. A TSM APAR s required (IY80002) that has yet to be released. This APAR is expected to drop in late March. (This should not be a surprise - it is documented in the TSM docs.) - A podcast explaining some of the new features in HACMP 5.3 is now available: http://www.ibm.com/systems/p/ha - A new redpaper on HACMP DLPAR & Virtualization was just released. It's essentially Chapter 10 of the new HACMP cookbook; released on 30-"Dec-2005: Cookbook:... [More]

Setting the title on a running aixterm To set the title of your current aixterm window you can use the echo command to output an Escape, left square bracket, number 2, semicolon, the text for the window, and the octal 007.

The new "multibos" command (AIX 5.3 ML3) provides dual AIX boot from the same rootvg. You can run production on one boot image while installing, customizing or updating the other. This is conceptually similar to AIX's "alt-disk-install". However, in "alt-disk-install" the boot images must reside on separate disks and separate rootvg's. The "multibos" capability allows both OS images to reside on the same disk/rootvg, avoiding the need for a separate disk. For more information see... [More]

We found it was taking from two to three hours to run the configure script for apache. After searching we found that the solution was to change the environment variable CONFIG_SHELL to point to a different shell than the default ksh. When this was done, the multi-hour run of ./configure was done in 3 minutes. Solution: From the Mozilla site for AIX it says: export CONFIG_SHELL=/opt/freeware/bin/bash export CONFIGURE_ENV_ARGS=/opt/freeware/bin/bash ./configure From testing, I found I could also use ksh93 and get similar results. export...

LPARmon Version 2 is now available from IBM Alphaworks. This free tool provides a graphical interface for viewing partition performance. The tool was developed by Austin's Briefing Center to demonstrate Advanced Virtual Partitioning, in particular to demonstrate free pool utilization in a micropartitioned server. I highly recommend it. http://www.alphaworks.ibm.com/tech/lparmon?open&S_TACT=106AH62W&S_CMP=NEWS
